Safe Emulsion Explosives for High Temperature Deep Level Mining

该项目旨在开发一种新型乳化炸药，这种炸药不受极深矿井中高温和活性岩石条件的影响。这些乳液将含有可调节的聚合物网络，以防止乳液柱在高温矿井的热井口中坍塌，沿着添加剂以消除与岩石的放热反应。如果不加以防止，该反应可能导致乳化液过早爆炸或爆燃，从而造成致命伤害并产生有毒的NOx气体。预计项目的成果是，增加经济和安全开采的深层矿石量，从而产生更大的出口收入和更多的就业机会，并减少大气污染。

This project aims to develop a new class of emulsion explosives, which are not susceptible to hot and reactive rock conditions in very deep-level ore mines. These emulsions will contain a tuneable polymer network to prevent collapsing of the emulsion columns in hot upholes in high temperature mines, along with additives to eliminate the exothermic reaction with the rocks. If not prevented the reaction can cause premature detonation or deflagration of the emulsion causing fatal injuries and generation of toxic NOx gases. Increase in economically and safely extractable deep-level ore volume that generates greater export earnings and more jobs are expected project outcomes, as is reduced atmospheric pollution.
